Answer:
The answer to your questions radius = 14 in
Step-by-step explanation:
Data
Circumference = 28π in
radius = ?
Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2π radius
-Solve for radius
radius = Circumference /2π
-Substitution
radius = 28π / 2π
-Simplification
radius = 28/2
-Result
radius = 14 in
Volume of a pyramid is (L * w * h) / 3
L=10 and w=10
h can be found by using the Pythagorean theorem:
divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)
a=h=12
we plug these numbers into the formula for the volume of a pyramid and get:
400
The answer would be 1.85+x=5.30
Answer:
Total area = 51 in²
Step-by-step explanation:
Section the shape into a rectangle and a triangle.
Area of a rectangle = width x length
⇒ area = 6 x 7 = 42 in²
Area of a triangle = 1/2 x base x height
⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²
Total area of composite shape = 42 + 9 = 51 in²
